Tree work can be dangerous

Removing or even Trimming a Tree Can Be Dangerous

 
When you see a professional company trim or cut down a tree, they often make it look fairly easy. That’s because most Tree Service Professionals have years of experience, and and the best have decades of experience. But even with the best equipment and years of experience, every Tree Service company SHOULD BE FULLY INSURED.
 
Don’t be fooled. Trimming trees, and especially cutting trees down can be very dangerous. With limbs that can weigh in excess of 1,000 pounds, the laws of gravity can take over unexpectedly during the process. Having the proper equipment to handle the job, such as a bucket truck and commercial-grade chainsaws, is just part of the process. Being able to carefully remove every limb or trunk section requires specific skills and ample experience.
